7 Claims. 1

Our invention relates to pressing machines of the industrial type and more particularly to improvements in pressing machine pad covers. In the usual commercial pressing machine a hollow buck is provided whiohhas a plurality of passageways or apertures communicating `with the interior of the `buck to permit passage of steam and air into and out of the buck throughV thepassageways. The top of the buck is provided with a plurality of pads usually of cotton or wool padding and a separate cover is arranged over these pads. The cover may be retained by springs or a combination of springs and rods and ropes or cords passing through a seamed fold around the cover when the edges and ends of the cover are tucked around the sides and ends of the buck. The steam and air Dads and cover.

The usual pad cover and its retaining means are open to a number of real objections. Because of the uneven tension and pulling of the edges and ends of the pad covers over the pads and the edges and ends of the buck, wrinkles are introduced in the pad covers. These Wrinkles reduce the Working area of the pressing pad covers and cut production. In addition large steam losses are introduced due to the fact the creases provide natural passageways to release steam which comes up through the pads, this steam being di-` rected in part toward the operator, causing discomfort. VThis also results in lowering steam pass through the (01. 3ra-ist)v pressure. Also, because of uneven tension produced by the conventional tensioning means, un-

stable surfaces are provided on the buck or` pad due to the uneven pressure built up under the pad cover When some portions of the cover are more tightly pulled against the pad than other portions. These creases also result in creasing any silk or like cloth materials being pressed. This uneven tensioning of the cover also results in uneven drying when air is sucked through the pad into the buck, Furthermore, in the exposed ends of the usual spring elements catch on garments on the buck. The number of springs required for a passable retaining means in the usual arrangement are many. Also with the usual arrangement pads on the buck are also subject to` slid"` A more specific object of our invention is to proy vide a novel pad cover which though employing Springs for tensioningA purposes provides evenY tension alongthesidesand ends of the pressing cover, reducing the tendency to wrinkles and thus increasing pressing area and production.

Another object` of our invention is to provide a i pressing pad cover of improved Vdesign in which p steam losses 'arereduced and the pressing surfacesare stabilized, thus reducing creases in silks andthe like. l A furtherobject of our invention is toso arrange `the tensioning springs and cover that the 1 exposed'fastening hooks are eliminated, thus preventing catching on garments being pressed.

Another object of our invention is to provide a y cover of the type described which will prevent i sliding of pads.

'A still further object of our invention is. to provide a `novel pad cover and tensioning device in Which the tensioning is equalized throughout and in which the number of retaining springs is reduced to a minimum.

' These and other objects will appear hereinafter.

The novel features which we believe to be characteristic of our invention are set forth with particularity in the appended claims, but the invention itself will best be understood by reference to the `following description taken in connection with the 'accompanying drawing in which Figure 1 is an end view of one conventional type of industrial pressing machine, Figure 2 is a longitudip nal'section taken along the line 2--2 of the buck and pad shown in Figure 1, Figure 3 is a cross sectional'view taken along the line 3-3 of Figure 2, Figure l is a layout cfa cover made according to our invention, Figure 5 shows `a detail oi constructiom Figure f6 shows the underside o1 `the buck with` a cover made according to our inven-` tionin use and Figure 7 shows a detail to explain a suggested theory `of applicants invention.

Referring to the drawings, in Figure l the usual industrial pressing machine` is provided with aA supportingffrarne lil on which is mounted the buck I I. having the usual pressing element comprising the elongated hollow pressing member I2 having thejchamber 2l] and on which is mounted the padding 23 covered with the usual cover 22.

The upper pressing element I3 is pivotally mounted `at I4 and operated by means of the link mechanism I6 and foot lever I5. Steam can be directed to the hollow member 2|) through conduits I8,`the"steam being controlled by a lever I9.

As bestshown in Figures 2 and` 3,the hollow member I2 is provided with Aa plurality of equally spaced apertures 2I which permit steam to estheresulting flaps covering theqriv the .eyelets Or'riy'ets lsl"4 asjnirlqieatedg the e eliminating all creases providinga in production ispr'od Y 3 ding 23 and cover 22, Springs I2 Vmay hold the cover in place.

In Figure 4 we show a cover made according to Y our invention prior to its completion and posi tioning on the buck. c This cover designated generally at 22 has the usual elongated shape and rounded ends, the ends being provided with theV iiops 22' o nol 2.2 which Whellewedwhowll in Figure Gprovideperipheral pockets for receiving the ends ofthe buck and also folds or channels which receive a draw cord shown generallyV at 36 in Figure 6. f
